Disk write protection error

What is DISK-WRITE-PROTECT-ERROR?

Windows cannot write to the disk due to write protection. This can occur on USB drives with physical write-protect switches, SSDs with failed controllers entering read-only mode as a self-protection mechanism, or drives with incorrect registry settings. The disk appears operational but all write operations fail silently or with error 0x80070013.

Common Causes

• SSD controller entering protection mode
• USB write-protect switch enabled
• Registry write-protect flag set

Step-by-Step Fix Guide

• 1
  Check for physical write-protect switch on device

  The diskpart command sequence is the most reliable method to remove software-based write protection.

• 2
  Remove write protection via diskpart

  If the drive has entered hardware write-protection mode due to controller failure, the drive must be replaced.

• 3
  Update SSD firmware
